This Mod Puts in 54 More Unique weapons. Note that you have to find these Unique Weapons as they are scattered throughout the map, some of them are tough to get (Worth it if they are very good weapons for example, the Gatling Laser) and some of them are easy to get (For example, just entering a random building and seeing it here.) If you want the Unique Weapons in Advance, I have a list of the locations of each Weapon,  shows the Stats, Names and some Tips if you want to find that specific weapon.
NOTE: I'm really sorry about not making the unique melee weapons mod. I have been busy with school and now that I'm free, I might make it. Maybe. I dunno, i'm really lazy and unpredictable. Which is a bad thing, I guess.

Thanks to lctlct/cx405 for making a patch of the weapon "Sorrow"!

EDIT: I will Make a More Unique Melee Weapons Mod and will start September. Probably would finish the mod by the Beginning of October. Stay tuned ;)

I will display 10 Unique weapons that are my personal favorites. (These are only 10 out of 54 Unique Weapons I'm Showing. You can see all of them in the Readme.)
Weapons:
Penitence - Ranger Sequoia - More Damage, Higher Fire Rate and Less Spread - It's a Unique Ranger Sequoia, a RANGER SEQUOIA. So Very Powerful <3

Sorrow - Light Machine Gun - High Damage, Low Fire Rate, Uses .50 MG Ammo, Less Weight - A Very Interesting Gun since It has a lower rate of fire, it uses .50 MG Ammo that are extremely rare. But it makes up for it with it's HIGH Damage. Very Powerful and then again not too powerful gun that is very satisfying but expensive since .50 MG is very rare. (Anti-Materiel Rifle Ammo)

Elite MSR Rifle - Sniper Rifle - More Damage, Scares Enemies, Higher Fire Rate - This. Gun. I love it since it has a slightly higher rate of fire than the Gobi Scout Campaign Rifle (Slightly), More Damage, and most importantly, It makes Enemies Flee when you get a critical hit. Also it's not that overpowed since the Critical Hit Chance is a bit Low so it's balanced.

Dr. Silence - Silenced .22 SMG - "A Murder a day keeps the Doctor Away..", Bonus

Limb Damage and Critical Hit Chance and More Damage - This gun is so satisfying (Even the Default one itself) and it's massive limb damage and critical hit chance make up for its Low damage. A Absolute must have.

Presto! - Lever-Action Shotgun - More Damage, Less Ammo Capacity, Disintegrates Enemies on Death - God I loved making this gun. This Gun does HIGH Damage for a shotgun  but has a ammo capacity of 3. The Thing that is so cool about this gun is how it disintegrates enemies on death. It doesn't really help you with anything except for looking satisfying as hell; Watching as your enemy disintegrates into a pile of ash. Amazing.

Tri-Shot - Laser Pistol - Shoots 3 Laser Beams, High Rate of Fire, More Durable - It shoots 3 laser beams. Basically the Tri-Beam Laser Rifle in Pistol Form. Nuff' Said.

Atomizer - Laser Rifle - "A True Example of...A Devasting Energy Weapon" and 
Exterminator - Plasma Rifle - "A True Example of...A Devasting Energy Weapon". These two guns are interesting but YOU the reader decide which gun is the superior to you. Interestingly Enough, The Atomizer does half the damage as the Exterminator

yet has twice the fire rate as the Exterminator. Exterminator uses 4 MF Cells per shot so it burns through ammo quicker yet the Atomizer has a lower Critical Hit Chance. Basically both guns do the same Damage and have their downsides and upsides. It's basically up to you to choose which gun is more appealing to you.

Quad-Shot - Tri-Beam Laser Rifle - "When 3 Beams aren't Enough" - 4 Laser Beams. Nuff' Said.

Grand Cannon - Tesla Cannon - "The Reason." - I don't have a real good reason for Liking this gun other than the name and the gun itself.
